DESCRIPTION

This device is particularly intended for applications

where multiple carriers must be amplified simulta-

neously with very low intermodulation products. It

has been mainly designed to fit with ADSL

chip-set such as ST70134 or ST70135.

The TS635 is a high output current dual operation-

al amplifier, with a large gain-bandwidth product

(130MHz) and capable of driving a 25

Ω load at

12V power supply. The TS635 is fitted out with

Power Down function in order to decrease the

consumption.

The TS635 is housed in a SO8 plastic package

and a SO8 Exposed-Pad plastic package.

APPLICATION

Subscriber Line (ADSL) (NT).
